wnENcHQ To all whom it may concern! Be it known that I, JOSEPH T.Rrc'rmr, a

' citizen of the United States, residing'at Port the fulcrum point ofthe pivoted aw. Another object .is the provisionof a wrench of thischaracter in which the fixed jaw i sojformed as to receiveand house theportion of the ivoted jaw.-

;simple and inexpensive in manufacture,

Clinton, in the county of Ottawa and. State P of Ohio, have invented newand useful Im rovements in Wrenches,".of 'which the folowing is aspecification; ,7 ThIS inventionrelates to wrenches, .par-

ticularly to wrenches adapted for use upon. nuts, bolts, and similarangular surfaces, and is furthermore adapted for use upon cylin-'drical'yobjects", such as pipesjan d v the like;

' A' very importantobject is ,the provision of a wrench of thischaracter'which has its ivoted j aw adjustable in respect toits fixedaw, whereby pipes or cylindrical 'objec'tsof difi'erent diameters maybeoperated upon,

holes 14 but which have flattened sides 17.v t The thickness of thetrnnnions 16between' thefiat'sides 17 is the same as the width of theadjustment being efiected by shifting member and handle associatedtherewith is major "A further 0 ject isthe provision of a wreneh'of thischaracter which will be very highly efiicient and durable in -use, and ageneral improvement of the art. With the above and other objects andadvantages in view, the invention consists in the novel construction andarrangement of parts to be hereinafter more fully-described and claimed,and illustrated in the" accompanying drawing, in 'which: Figure 1, is aperspective view of my wrench, the'parts being separated, and Fig. 2 isa cross sectional view there-v through' on the line 2-2of F 1.- 1"Referring moreparticularly to the draw ing, the numeral 5 designatesthe fixed jaw member as a whole, which comprises the hamdle ortion. 6and-the work engaging portion 7. he p0rtion7- is curved-on its inner andouter edges, as shown, the curvature of the inner edge permittingapplication of the wrench to articles or work without theedgeinterfering therewith; The end portion 7 is formed as a hook whichhas its bill directedsomewhat toward the other end 6, as shown at 9. Thehandle portion 6-ofthis fixed jaw member is slotted throughout thegreater portion of its length, as shown at'10.

It will'be seen that I have-provided means whereby the movable jaw '12may be'adjusted in relation to'the fixed jaw member 5. In carrying-outthis feature of the invention, I provide the handle portion 6 with aplurality of circular openings which communicate with transverse slots15 extending to the inner edge of the fixed jaw member 5. holes andslots are'in the nature of key-hole slotsand-it will be. observed thatthe length of the slots-15 increase progressively toward the end of thehandle portion 6. Extending from opposite sides of the jaw member12"are'trunn1ons 16 which are substantially cylindrical and of the samediameter as the the slots 15 so that the trunnions 17 may be passedthrough the slots 15 and into the holes 14. It isunder'stood of course,that the jaw member-12 must be disposed at right angles to the inneredgeof the jaw member 5 in order that the trunnions may be insertedwithin the slots. After the trnnnions have been. inserted within theselected holes, the jaw member 12 is swung toward the end 71of the fixedjaw member, whereby dislocation. of the trunnions will be prevented. Thewrench may'then be used in an obvious manner by engaging the hooked end9 of the fixed jaw member at one side of the object to be-turned and thetoothed end 13 of the movable jaw member at thevother side. In

' case cylindrical objects of relatively great diameter are to beengaged by the wrench, the trunnions 16 are engaged within the holes 14nearest to the end of the handle member 6. a 3

When the wrench is not in use and'the trunnions- 16 are inserted in theholes 14: nearest the end of the handle member 6, the jaw 12' wi1l bedisposed entirely within the slot 10 with the exception of its curvedend 13 and. the outer edge of the jaw member 12 will be flush with theopen edge of the jaw member 5.

' From the foregoing description and a study, of the drawing, it will beapparent that I have thus provided a very simple and efiicient wrenchwhereby angular or cylindrical objects may be gripped and turned andwhich is adjustable for satisfactory use upon objects having widelydifferent dimensions.

These curved and provided with teeth, as shown Having thus described myinvention, what I claim is:

1. A wrench comprising a fixed jaw member terminating atone end in ahook and having at. its other end a handle portion longitudinallyslotted throughout its length at; its inner edge, said handle portionbeing provided with a plurality of transversely extending circularopenings and further brovided with a plurality of slots communicatingwith the circular openings and extending to theinner edge of the handleportion and inclined toward said hook, a movable jaw member disposedwithin said longitudinal slot and trunnlons extending laterally fromsaid movable jaw member and dis-- fi- BEST AVAILABLE cop 9.

In testimony whereof I aflix my signatur JOSEPH T. RICHEY.
